Question

Solve for x: 5x + 2 = 4x − 9. (1 point) 7 −7 11 −11

Answer 1

x = -11

Explanation:

`5x+2=4x-9\qquad\text{subtract 2 from both sides}\\\\5x+2-2=4x-9-2\\\\5x=4x-11\qquad\text{subtract}\ 4x\ \text{from both sides}\\\\5x-4x=4x-4x-11\\\\x=-11`

Answer 2

x=-11

Explanation:

First you subtract 4x from both sides: 5x+2-4x=4x-9-4x, so then you have x+2=-9

then you subtract the 2 from both sides: x+2-2=-9-2

And that gives you x=-11
